I purchased this light. [Link: amazon.com] (very good light output FYI)
and replaced the Motion Sensor with [Link: goodmart.com]

That sensor has relay outputs so I can get the feedback from it. I had spare conductors at my garage door sensor's that I was able to tap onto. Now all I need to do is replace the switch with a Crestron dimmer, and have the motion bypassed. (all I need is the feedback), logic will dictate the behavior.
